It is.

[Problem that the invention seeks to solve]

The present invention makes it possible to make an international call through a long-distance telephone exchange by using a series of sequence means in which all responses to the telephone office and instructions based thereon are stored and registered. This system provides a means to eliminate the complexity by automating the entire process from calling the central office to responding to the other party.

〔Example〕

The structure and operation of the embodiments of the present invention will be explained below.

First, the circuit diagram in FIG. 1 and the flowcharts in FIGS. 2 and 3 will be explained.

In Figure 1, Ll and L2 are telephone lines,
2 is a connecting part consisting of a line transformer, etc. that connects the telephone line and this device, 2 is a 1-chip microprocessor (CPU), and J(O) has a built-in program.
Built-in M (read-only memory). Further, 3 is an R, AM (random access memory) that stores multiple telephone numbers, and is backed up by a battery BAT as a measure against power outages. 4 is a keyboard, and the numeric keypad is used for manual dialing. You can select 1 from among the multiple phone numbers stored in the AM3 above.
A selection key 4-1 for selecting one telephone number, a dialing key for automatically dialing in a predetermined order based on the telephone numbers selected by the selection keys, and a dialing key for registering telephone numbers in R and AM3 above. It consists of a registration key 4-3, which is used, and a deletion key 4-4, which is used when deleting a telephone number that is no longer needed among the plurality of telephone numbers registered in the 1'LAM 3. Reference numeral 5 denotes a display section, on which a telephone number is displayed when selecting, registering, etc. the above-mentioned telephone number. 6 is a 400 Hz filter for detecting a multi-frequency main signal when the above-mentioned numeric keypad is pressed. Reference numeral 8 denotes an amplifier circuit, which, together with the speaker 9, can monitor the response of the called party.

Next, referring to FIGS. 1 and 2, a means for registering a telephone number in the RAM 3 shown in FIG. 1 will be described.

First, when you press the registration key 4-3, the ROM in the CPU2
The built-in program calls the subroutine shown in FIG. In step 820, the RA
The telephone number recorded in M3 is searched, and the registration number of the newly registered telephone number is displayed on the display unit 5 as shown in FIG. 2-1. In this embodiment, the registration number "Pa0:" records the phone number of the owner of this device, and the registration number "'1;" records a special number for calling the station, such as "o 05 q"'. Registration Number II 2. If a telephone number is already registered in II, the registration number "3:" for the newly registered telephone number will be displayed as shown in Figure 2-1 above.

At the same time, the message ``Enter your phone number'' that instructs you how to operate is displayed in kana.In step 821, the registration number a
t3. Set the start address of memory for pp.

In the next step S22, a test is performed to see if "゛", which is used as a delimiter signal for telephone numbers input after a series of telephone numbers has been inputted, has been input.Until the series of telephone numbers are inputted. Since step S22 is negative, the process moves to step 823, where a one-digit telephone number is input using the keyboard 4 in FIG.
), and the address of the next one-digit phone number Nodamemo January % AM3 is incremented by +1.

In the next step S26, the meaning of ``Please input the number when you have finished inputting the telephone number'' is displayed in kana as shown in Figure 2-2. Since steps 826 to S22 form a loop, the input of a series of telephone numbers is completed, and when @% #17 is input, the subroutine shown in FIG. 2 is completed. Alternatively, a speed dial may be registered instead of this telephone number.

Next, the automatic dialing operation using the telephone number registered as described above will be specifically explained with reference to the flowchart of FIG.

In order to perform this auto-dial operation, as mentioned above, please note down the phone number of the owner of this device, the special number for calling the station, such as "0059", and one or more phone numbers of the called party.IJ)tAM3 It is necessary to be registered in . If multiple telephone numbers of the called party are registered, it is necessary to select the central telephone number of the called party using the selection key 4-1 in Figure 1. Since the means are well known, a flowchart is omitted.

Now, when the transmission key 4-2 in FIG. 1 is pressed, the subroutine shown in FIG. 3 is called. In step 830, relay Y- connected to output port 0-5 of CPU2
1 on, and connect the relay Y-1 contact (
(not shown) to connect the telephone lines Ll and L2.

At this point, a dial tone is sent from the station to the device, so this is tested in step 831. When this dial tone is detected through filter 7, step 8
32, the special number "OO59" is transmitted to the telephone lines L1 and L2 via the output ports 0-3 of the CP'U2, the D'I'MF oscillation circuit 6, and the coupling section 1. When the station recognizes this special number, an intermittent signal of 400 Hz is sent from the station to this device, and this is detected by the program via the filter 7 (step S33). When this intermittent signal is detected, the process moves to step 834, and a call is made with the phone number K of the owner of the device added.

When this call is completed, the telephone line is temporarily disconnected (step 35).

Next, the device waits for a call from the station.

When the station side is ready, the device will be called back using the phone number of the device registered on the station side as described above. The ring signal is then tested in step 836. This call signal is transmitted from output terminal 0-3 of coupling section 1 in FIG.
It enters input port ■-4 of P U 2 and is detected by the program. Now, when the ringing signal is detected, step 8 described above
30, the telephone line is closed (step 537).

Next, the station sends a message saying "Please dial the telephone number of the 6th party using a talkie."The station accepts the telephone number both during and after the talkie has been transmitted, so step 838 is sent. When the voice of the above-mentioned talkie is detected (in this embodiment, only the presence of a signal is detected, but the voice recognition is used to detect the voice of the above talkie).
The process moves to an input step 839 in which the voice "dial" can be detected, and the "°arrow"' is transmitted for the first time as in the registration described above.While the station is transmitting a talkie, the above u arrow II is transmitted. Since the talkie of the station is interrupted when the voice of the station is received, this test is performed in step S40.When the talkie voice is interrupted, the process moves to step S41, and the telephone number for calling the selected called party is entered as described above. is auto-dialed, "su" is added to the end, and the process moves to step 842.

In step 842, the output ports 0-4 of CPU2
The amplifier circuit 8 is activated by a signal from the callee, and the response of the called party can be confirmed using the speaker 9. In other words, the ringback tone that is calling the called party is initially heard from the speaker 9, but when the called party answers, the called person's voice saying "Mo7mon" can be heard. When the telephone 'rE I goes off-hook, the above-mentioned off-hook is detected by the output of the output port 0-2 of the coupling unit 1, the relay y-1 is restored, the telephone line is closed with only the telephone equipment, and mutual communication by the telephone is performed. Enables a call and turns off the monitor from speaker 9 (step 843
．． 544).

Note that it is also possible to provide a changeover switch to this device so that it can be used by switching to a commercially available normal autodial instead of the above-mentioned special autodial.

〔effect〕

As described above, this device eliminates the complexity that callers encounter when making overseas calls outside of large cities, namely the inconvenience of having to proceed one step at a time according to instructions from a local station before calling the other party. However, it is now possible to automatically call the other party, and has the practical effect of ensuring reliable operation without worrying about failure during the process.
